Keep them within easy reach, like the driver door pocket.
Changing glasses while driving on a high speed lane is dangerous regardless of where you put your spare glasses
This cannot materialize quickly enough.

If they are replacing bifocals, the wearer needs both a near- and far-sighted prescription. Far-sighted only would never need these. Either failure mode would be dangerous while driving because you need to be able to read your dash.
It's not a crisis if you cannot read your dash. How often do you look at the oil pressure gauge, for example? As for speed, just move with the traffic.
If you want to talk specifics, you’re supposed to be able to see your speed and how your car is performing. You should be prepared for contingencies, like your temperature changing or a yellow/red warning on the dash. You may need to deal with a problem in the car, like grabbing something that could slide under the pedals.
The same goes for farsighted driving. Yes, in most cases you could just follow traffic and you wouldn’t need to read street signs or look at traffic a mile ahead. But you need to be prepared for unexpected situations, and you’ll generally do worse just mentally managing your reduced vision.
I’ve driven without my glasses and tested an unexpectedly bad trial prescription in a car, if it matters.
Looks super cool! > It still needs to obtain the necessary medical certifications in order to sell its glasses and get all the production pieces in place Oh, ok. I hope they have enough funding to last till the FDA clears them, in 2030 :/ The same organization which allows any snake oil to be marketed as long as they say it’s a “supplement” will hold a pair of glasses up for years, as though there could be a hidden d…
There is potential danger with a lens that can suddenly change to a second prescription. For example: imagine you're driving and your whole field of vision suddenly starts flickering in and out of focus. That would be incredibly distracting and pretty dangerous. Even if they just started focusing on 1 foot away it'd be quite bad.
There are plenty of FDA-approved drugs that should not be taken while operating a motor vehicle.

You mean the rule that’s basically “Anything goes” as long as you reproduce the magic incantation in tiny print at the end: “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.”
That's not how it works.
I pray for the next major development in glasses tech to be some thing that blocks ultra-bright oncoming LEDs while driving.

Why not in the windshield?

Plenty of us are simultaneously far and near sighted. I can't drive without glasses, but until I got progressive lenses I couldn't use my phone with my glasses on.
If you cannot drive without glasses, the sensible thing is to keep a backup pair in the car. After all, glasses can fall off and get lost under the seat, get stepped on, etc.
It is also a requirement for international flight operations under ICAO regulations. I’m pretty sure this regulation (or something close to it) is enforced by just about every flight-licensing authority worldwide.
It’s plain good sense and I’m glad it’s in there. A plane cannot pull over to the side of the highway while the pilot fumbles around trying to dig his glasses out from under the seat :)
(As a side note, this rule isn’t just for dropped spectacles: there have been cases where they literally get sucked out of the airplane if a cockpit window fails or where a bird strike causing facial injuries also damages the pilots glasses).

Then perhaps tell us how it works, rather than just being negative toward other people's comments.
